摘　　要：使用一种新型中温固化剂和高效活性增韧剂,制备了一种适合膜壳湿法缠绕用的中温固化环氧树脂。对树脂基体及其复合材料力学性能和耐水性的研究表明,该树脂体系具有许多优良性能：室温下其黏度较低(约0．75～0．95 Pa·s),适用期很长(≥6 h)；力学性能优良；在70℃以上可凝胶、固化；制得的膜壳爆破时纤维强度转化率高达82．8％,耐疲劳达15万次而无损伤。此外,室温下在水中浸泡360d后其吸水率低于0．95％。结果表明,该中温环氧体系完全适用于反渗透膜壳湿法缠绕使用。A novel epoxy resin suitable for filament wet-winding of pressure vessel for reverse osmosis was developed and used in a composite based on a middle-temperature curing agent and a highly effective reactive toughener. The epoxy resin possessed a low viscosity （0.75- 0.95 Pa·s） and longer pot life （≥6 h） at room temperature, good mechanical properties, and can be cured at 70 ℃. The blast and fatigue measurements demonstrated the strength conversion ratio of the glass fiber was 82.8 %, and the fatigue resistance reached 150 000 cycles. After soaked in water after 360 days, the water absorbence was less than 0.95 %.
